I am a little worried about the customs in Mexico too. I was wondering about our rings and IPOD and IPOD speakers, do you ladies think I would need to bring receipts for these items? I googled the topic and found this website: Mexico Entry Requirements & Customs - Travel - LATimes.com
and it said:
To avoid paying duty on foreign-made personal items you owned before your trip, bring along a bill of sale, insurance policy, jeweler's appraisal, or receipts of purchase. Or you can register items that can be readily identified by a permanently affixed serial number or marking -- think laptop computers, cameras, and CD players -- with Customs before you leave. Take the items to the nearest Customs office or register them with Customs at the airport from which you're departing. You'll receive, at no cost, a Certificate of Registration, which allows duty-free entry for the life of the item.
Anyone planning to get this "Certificate of Registration"?
